Definitions

  • My invention relates to braiding machines having two rowsof bobbins crossing each other in opposite directions, the inner bobbins being continuously driven by avroller system, and my invention more particularly consists in a machine embodying the novel coniibination of a roller system and a guide track for the bobbin slides, which combination gives a valuable new result; tliusthe power required for driving the bobbin slides upon their track is lessened in a considerable degree, and the inner bobbins are securely guided by the slides and the slide track. In that way a much smaller pressure than heretofore ⁇ is put on the outer threads during the passage through the roller system, the machine runs more easily and its construction is greatly simplified.
  • the double ⁇ roller systein In a machine where inner bobbins are continuously moved around the braiding axis by a roller system which operates witliouta slide guide for the inner bobbins, the double ⁇ roller systeinconsists in rollers appliedto both ends of the inner .bobbins, whereby the inner bobbins are driven and at thesame time maintained in their position relative to the braiding centre. Because of the drive rollers being disposed above the roller path my new machine has the ad ⁇ vantage of requiring only a small expenditure of power for driving the nnerbobbins.
  • the present invention combines the advantages of both types of machine without the disadvantages thereof. llhile the inner bobbins aresecurely guided by slides upon a guide track7 the axles of the drive rollers are arranged above the roller path, so that the driving angle and therefore the power components directed upwardly at right angles to the guide path is reduced to zero sparing the outer threads to an extraordinary degree and allowing an easy running of the machine.
  • a further object of my invention is to so connectthe slide rollers to the slidesl that they always bear completely upon the roller path, as .for instance, by gravity, the rollers being inovably guided in the slides. This is preferably effected by pins inserted in the slides.
  • the sliderollers however may also be connected to the slides by linked intermediate members. The pressure of the slide rollers upon the roller path may be increased by springs.
  • Figure l is a vertical section through a braiding machine embodying the invention and in which figure, for the sake of clearness, only two inner bobbins and one outer bobbin are shown.
  • Figure 2 is a view as seen from the inside of the roller system on -tlie surface ofthe cone marked c in Figure l in which the path of the outer thread relative to the rollersystem is shown.
  • Figure 3 is a fragmental view as seen from the outside viewed in the direction of the arrow m in Figure l, showing the outer thread guideand the travel of the outer thread relative to the moving slide track.
  • Figure 4 is a plan of a bobbin slide and slide roller viewed l.
  • Figure 5 is a vertical section drawn to a larger scale, of a portion of the braiding. machine in which for greater clearness sake only one slide roller and one inner bobbin are shown as well as one drive roller only shown as being in the same plane with theslide roller.
  • the drive roller lies in reality sidewise relative to the slide rolleras can be seen in Figure 7
  • Figure 6 is a section in the direction of the arrown in Figure 1 -outer thread guides each consisting nof a roller 3 and a rocking lever 5 ( Figure 3).
  • the Ycarrier 7 which also carries the guiderail 41 for the bobbin slides 37 is moved around the braiding axis by means of the bevel gear 3l secured to carrier 7 by the bevel gear 36 on the driven shaft 29.
  • the slides 37 carrying the inner' bobbins 20 and moving in opposite direction to the guide rail 411 are driven in the following manner by the roller system. y
  • the bevel gear 36 is also in mesh with a bevel gear 42 (Fig. 1) which is situated opposite bevel gear 34k and therefore rotates in i opposite direction to vthe bevel gear 341.
  • vbevel gear 42 is secured to a hollow shaft rotatably journalled in the stationary center bearing 17.
  • the upper end of shaft 25- supports the roller carrier 26 which carries the .axles 31 upon which rotate the driverollers 430 for driving the bobbin slides 37 upon the guide rail 411.
  • This rotation is effected by causing the slide rollers 23 to run ⁇ upon :a track 33 formed on 4the carrier 7, the slide rollers in their turn rotating the drive rollers 30 due to the driving fricltion so that the outer threads pass without being twisted between track 33 and slide rollers 23 and between the slide ⁇ rollers 23 and the drive rollers 30.
  • axles 22 of rollers 23 are connected to their slides 37 by links 28 through pins 152, see Figure 2, so that the rollers 23 will bear through gravity upon track 33.
  • the spindles of bobbins 20 may either be connected direct with vthe axles 22 ofV the slide rollers 23 0r may be separate and carried by an arm 60 secured to a thread guide rod 50 as shown in Figure 4.
  • Figure 2 shows the direction of the continuous drive of axles 31 of the drive rollers 30 relative to the ⁇ axles 22 ⁇ of the slide rollers 23 and the direction of motion of three slide rollers 23 and of a slide 37 upon the guide rail 41.
  • the driving angle a between both said directions is about half as great as in the usual construction with inner bobbins guided by slides where the angle a has usually been about 50". If the driving force of an axle 31 to an axle 22 were divided into two :torce components of which one lies in the ⁇ ,direction of the slide moven'ient and the other at right angles thereto it would be found that compared with the old construction there would be a very considerable reduction Iof lost foce components upwardly directed at right angles to the direction of movement of the slide.
  • the angle a were reduced to Zero, then, the upwardly directed lost force components will also be reduced to Zero, which however would necessitate the outer thread path to become steeper which might have an unfavorable action on the velocit-y of the outer thread guide.
  • Figures 1 and l also show the well-known protecting shield 151 mounted on the spindle of the inner .bobbin 2O and having for its function to prevent the outer threads from touling the inner bobbins 2O but allowing them to slide if necessary on the per-iphery of the protecting shield 151.
  • Figures 1 and 3 4 show diagrammatically the rolls 3 rolling upon the curved track 8,; the rolls 3 are mounted upon their axles 2 eccentrically relative to a spindle 4e, Figure 3, thus giving the levers 5 which guide the threads coming from the outer bobbins 182l to and fro movement in well-known manner.
  • the rollers 3 are held in a well-known manner by a spring (not shown) in contact with the curved track S..
  • FIG. 5 yto 7. A modification ot connecting the slide rollers 23 to the slides 37 is illustrated in Figures 5 yto 7..
  • the axle 22 is secured to a bracket 1.60 mounted on a stud 161 which is movable in a bore in sli-de 37.
  • bracket 160 In order to prevent bracket 160 from turning on stud 161 in a horizontal plane, the bracket is arranged adjacent to one side oi slide 37 and is given an extensive surilace as can be seen from Figure 6.
  • the driving means comprising bracket 160 and stud 161. descends because of its own weight and that of the slide roll and inner bobbin until the slide roll 23 bears on the track 33.
  • the diagram shown in Figure 7 illustrates a braiding; ⁇ machine equipped with sixteen bobbins and one drive roll only between each two slide rolls 23; slide 37 is shown orv the lett hand side with bracket 160 and its stud 161 as well as the path 0 described by the outer thread relative to the rollers of the roller system.
  • a braiding machine having two rows of bobbins moving in opposite direction, carriers ior said bobbins and rollers for continuously driving the inner bobbins, the combination with said inner ⁇ bobbins, slides for guiding them and a track for said slides, of slide rollers, movable links connecting Said slide rollers to said slides, and a path or said slide rollers provided on the carrier for the outer bobbins, said drive rollers having their axles arranged above said path.
